Fyzicky neklonovatelné funkce / Physical unclonable functions

Hegr, Vojtěch January 2017 (has links)
The theme of the thesis is Physical Unclonable Functions (PUF). The following objectives were assigned: to provide a literature research concerning PUFs, to perform a property analysis to select appropriate type of PUF for implementation and to realize an authentication cryptosystem based on the chosen PUF. Based on the research, the cryptosystem was designed based on ring oscillator PUF. The proposed cryptosystem is tested in several scenarios with the maximal rate of successful authentication of 81%. The cryptosystem also allows to be used for device identification. Furthermore, the results were discussed and suitable improvements of design was proposed. Besides the cryptosystem itself, the thesis also introduced a unique comparison of existing types of PUFs.
